Dude! I totally say "totally" and "dude," too… xo
Like you & Meghann, I say "totally" and "dude" quite frequently. It's not even something I'm conscious about. If I'm not calling someone a "dumba**", I'm calling him or her a "dude" (doesn't matter if it's a woman or not). Oh well on the cookies. You're human. You're allowed to make mistakes. You also earned the money to purchase said cookies (or the ingredients to make said cookies). So there.
